Field-effect transistor chemical sensors of single nanoribbon of copper phthalocyanine

Abstract

Copper phthalocyanine (CuPc) nanoribbon field-effect transistors were implemented as chemical sensors. They showed fast response and high reversibility in the detection of the tetrahydrofuran atmosphere at room temperature. The drain current of the field-effect transistor sensor decreased from 6.7 to 0.2 nA when the transistor was measured under the tetrahydrofuran atmosphere. The sensor was self-refreshable in a few minutes. These results demonstrate that the organic single crystalline nanoribbon transistors could effectively act as chemical sensors.

Template‐Assisted Electrochemical Deposition for Organic and Hybrid Nanowire Electronics

“…In the past decades, 1D nanostructures of organic semiconductors [ 1,2 ] have attracted a great deal of research interest, due to their applications in miniaturized, multi‐functional photonic and electronic devices, such as optical waveguide, [ 3,4 ] nanolaser, [ 5–7 ] field‐effect transistor (FET), [ 8–10 ] photodetector, [ 11 ] and solar cell. [ 12,13 ] Noncovalent self‐assembly of molecular building blocks driven by ππ stacking and/or hydrogen bonding is one of the simplest methods to fabricate 1D organic nanostructures.…”

Iron phthalocyanine nanorods for ethanol sensoring

“…It is found that the gas-sensor performance of MPc strongly depends on its microstructure [19][20][21]. For example, copper (Cu) Pc nanoribbons based gas sensor showed high reversibility and response to tetrahydrofuran atmosphere [22]. Poly-Cu tetraaminoPc nanotubes as the sensor exhibited fast sensitivities and enhanced linear ranges [23].…”
